Symptoms of atopic eczema

There will usually be periods where the symptoms improve, followed by periods where they get worse (flare-ups). Flare-ups may occur as often as two or three times a month.

Atopic eczema can occur all over the body, but is most common on the hands (especially fingers), the insides of the elbows or backs of the knees, and the face and scalp in children. The face is more commonly involved in adults.

The severity of atopic eczema can vary a lot from person to person. People with mild eczema may only have small areas of dry skin that are occasionally itchy. In more severe cases, atopic eczema can cause widespread red, inflamed skin all over the body and constant itching.

Scratching can disrupt your sleep, make your skin bleed, and cause secondary infections. It can also make itching worse, and a cycle of itching and regular scratching may develop. This can lead to sleepless nights and difficulty concentrating at school or work.

Areas of skin affected by eczema may also turn temporarily darker or lighter after the condition has improved. This is more noticeable in people with darker skin. It's not a result of scarring or a side effect of steroid creams, but more of a "footprint" of old inflammation and will eventually return to its normal colour.

Signs of an infection

Occasionally, areas of skin affected by atopic eczema can become infected. Signs of an infection can include:

your eczema getting a lot worse

fluid oozing from the skin

a yellow crust on the skin surface or small yellowish-white spots appearing in the eczema

the skin becoming swollen and sore

a high temperature (fever) and generally feeling unwell

See your doctor as soon as possible if you think your or your child's skin may have become infected.

You should tell your GP if your condition is affecting your quality of life – for example, if you have difficulty sleeping because of itching, or your eczema limits your everyday activities.

Checklist for diagnosing atopic eczema

Typically, to be diagnosed with atopic eczema you should have had an itchy skin condition in the last 12 months and three or more of the following:

visibly irritated red skin in the creases of your skin, such as the insides of your elbows or behind your knees (or on the cheeks, outsides of elbows, or fronts of the knees in children aged 18 months or under) at the time of examination by a health professional

a history of skin irritation occurring in the same areas mentioned above

generally dry skin in the last 12 months

a history of asthma or hay fever – children under four must have an immediate relative, such as a parent, brother or sister, who has one of these conditions

the condition started before the age of two (this does not apply to children under the age of four)

Establishing triggers

Your GP should work with you to establish if any triggers make your eczema worse.

You may be asked about your diet and lifestyle to see if something obvious may be contributing to your symptoms. For example, you may have noticed some soaps or shampoos make the eczema worse.

You may also be asked to keep a food diary to try to determine whether a specific food makes your symptoms worse.

A food diary involves writing down everything you eat and making a record of any eczema flare-ups you have. Your GP can then use the diary to see if there is a pattern between your symptoms and what you eat.

Allergy tests are not usually needed to identify triggers, although they are sometimes helpful in identifying food allergies that may be triggering symptoms in young children or in those where a food allergy is suspected.

Other treatments include topical pimecrolimus or tacrolimus for eczema in sensitive sites not responding to simpler treatment, antihistamines for severe itching, bandages or special body suits to allow the body to heal underneath, or more powerful treatments offered by a dermatologist (skin specialist).

Self care

As well as the treatments mentioned above, there are things you can do yourself to help ease your symptoms and prevent further problems.

Try to reduce the damage from scratching

Eczema is often itchy and it can be very tempting to scratch the affected areas of skin. But scratching usually damages the skin, which can itself cause more eczema to occur.

The skin eventually thickens into leathery areas as a result of chronic scratching. Deep scratching also causes bleeding and increases the risk of your skin becoming infected or scarred.

Keep your nails short and clean to minimise damage to the skin from unintentional scratching. Keep your skin covered with light clothing to reduce damage from habitual scratching.

Avoid triggers

Your GP will work with you to establish what might trigger the eczema flare-ups, although it may get better or worse for no obvious reason.

Once you know your triggers, you can try to avoid them. For example:

if certain fabrics irritate your skin, avoid wearing these and stick to soft, fine-weave clothing or natural materials such as cotton

if heat aggravates your eczema, keep the rooms in your home cool, especially the bedroom

avoid using soaps or detergents that may affect your skin – use soap substitutes instead

Although some people with eczema are allergic to house dust mites, trying to rid your home of them isn't recommended as it can be difficult and there is no clear evidence that it helps.

Dietary changes

Some foods, such as eggs and cows' milk, can trigger eczema symptoms. However, you should not make significant changes to your diet without first speaking to your GP.

It may not be healthy to cut these foods from your diet, especially in young children who need the calcium, calories and protein from these foods.

If your GP suspects you have a food allergy, you may be referred to a dietitian (a specialist in diet and nutrition), who can help work out a way to avoid the food you're allergic to while ensuring you still get all the nutrition you need.

Alternatively, you may be referred to a hospital specialist such as an immunologist, dermatologist or paediatrician.

If you are breastfeeding a baby with atopic eczema, get medical advice before making any changes to your regular diet.

Emollients

Emollients are moisturising treatments applied directly to the skin to reduce water loss and cover it with a protective film. They are often used to help manage dry or scaly skin conditions such as atopic eczema.

In addition to making the skin feel less dry, they may also have a mild anti-inflammatory role, and can help reduce the number of flare-ups you have.

Choosing an emollient

Several different emollients are available. You may need to try a few to find one that works for you. You may also be advised to use a mix of emollients, such as:

an ointment for very dry skin

a cream or lotion for less dry skin

an emollient to use instead of soap

an emollient to add to bath water or use in the shower

one emollient to use on your face and hands, and a different one to use on your body

The difference between lotions, creams and ointments is the amount of oil they contain. Ointments contain the most oil so they can be quite greasy, but are the most effective at keeping moisture in the skin.

Lotions contain the least amount of oil so are not greasy, but can be less effective. Creams are somewhere in between.

If you have been using a particular emollient for some time, it may eventually become less effective or may start to irritate your skin.

If this is the case, your GP will be able to prescribe another product that suits you better. The best emollient is the one you feel happy using every day.

How to use emollients

Use your emollient all the time, even if you are not experiencing symptoms. Many people find it helpful to keep separate supplies of emollients at work or school, or a tub in the bathroom and one in a living area.

To apply the emollient:

use a large amount

don't rub it in – smooth it into the skin in the same direction the hair grows instead

after a bath or shower, gently pat the skin dry and apply the emollient while the skin is still moist to keep the moisture in

You should use an emollient at least twice a day if you can, or more often if you have very dry skin.

During a flare-up, apply generous amounts of emollient more frequently, but remember to treat inflamed skin with a topical corticosteroid as emollients used on their own are not enough to control it.

Don't put your fingers into an emollient pot – use a spoon or pump dispenser instead, as this reduces the risk of infection. And never share your emollient with other people.

Topical corticosteroids

If your skin is sore and inflamed, your GP may prescribe a topical corticosteroid (applied directly to your skin), which can reduce the inflammation within a few days.

Topical corticosteroids can be prescribed in different strengths, depending on the severity of your atopic eczema and the areas of skin affected.

They can be very mild (such as hydrocortisone), moderate (such as clobetasone butyrate), or even stronger (such as mometasone).

If you need to use corticosteroids frequently, see your GP regularly so they can check the treatment is working effectively and you are using the right amount.

How to use topical corticosteroids

Don't be afraid to apply the treatment to affected areas to control your eczema. Unless instructed otherwise by your doctor, follow the directions on the patient information leaflet that comes with your medication. This will give details of how much to apply.

Most people will only have to apply it once a day as there is no evidence there is any benefit to applying it more often.

When using a topical corticosteroid:

apply your emollient first and ideally wait around 30 minutes until the emollient has soaked into your skin, or apply the corticosteroid at a different time of day (such as at night)

apply the recommended amount of the topical corticosteroid to the affected area

continue to use it until 48 hours after the flare-up has cleared so the inflammation under the skin surface is treated

Occasionally, your doctor may suggest using a topical corticosteroid less frequently, but over a longer period of time. This is designed to help prevent flare-ups.

This is sometimes called "weekend treatment", where a person who has already gained control of their eczema uses the topical corticosteroid every weekend on the trouble sites to prevent them becoming active again.

Side effects

Topical corticosteroids may cause a mild stinging sensation for less than a minute as you apply them.

In rare cases, they may also cause:

thinning of the skin – especially if the strong steroids are used in the wrong places, such as the face, for too long (for example, several weeks)

changes in skin colour – usually, skin lightening after many months of using very strong steroids, but most lightening after eczema is a "footprint" of old inflammation and nothing to do with treatments

Generally, using a strong topical corticosteroid for many months, using them in sensitive areas such as the face, armpits or groin, or using a large amount will increase your risk of side effects. For this reason, you should be prescribed the weakest effective treatment to control your symptoms.

Antihistamines

Antihistamines are a type of medicine that blocks the effects of a substance in the blood called histamine. They can help relieve the itching associated with atopic eczema.

They can either be sedating, which cause drowsiness, or non-sedating. If you have severe itching, your GP may suggest trying a non-sedating antihistamine.

If itching during a flare-up affects your sleep, your GP may suggest taking a sedating antihistamine. Sedating antihistamines can cause drowsiness into the following day, so it may be helpful to let your child's school know they may not be as alert as normal.

Bandages and wet wraps

In some cases, your GP may prescribe special medicated bandages, clothing or wet wraps to wear over areas of skin affected by eczema.

These can either be used over emollients or with topical corticosteroids to prevent scratching, allow the skin underneath to heal, and stop the skin drying out.

Corticosteroid tablets

These are rarely used to treat atopic eczema nowadays, but may occasionally be prescribed for short periods of five to seven days to help bring particularly severe flare-ups under control.

Longer courses of treatment are generally avoided because of the risk of potentially serious side effects.

If your GP thinks your condition may be severe enough to benefit from repeated or prolonged treatment with corticosteroid tablets, they will probably refer you to a specialist.

Seeing a specialist

In some cases, your GP may refer you to a specialist in treating skin conditions (dermatologist).

You may be referred if your GP is not sure what type of eczema you have, normal treatment is not controlling your eczema, your eczema is affecting your daily life, or it's not clear what is causing it.

A dermatologist may be able to offer the following:

a thorough review of your existing treatment – to make sure you are using enough of the right things at the right times

A dermatologist may also offer additional support to help you use your treatments correctly, such as demonstrations from nurse specialists, and they may be able to refer you for psychological support if you feel you need it.

Complementary therapies

Some people may find complementary therapies such as herbal remedies helpful in treating their eczema, but there is little evidence to show these remedies are effective.

If you are thinking about using a complementary therapy, speak to your GP first to ensure the therapy is safe for you to use. Make sure you continue to use other treatments your GP has prescribed.

Complications of atopic eczema

People with atopic eczema can sometimes develop further physical and psychological problems.

Bacterial skin infections

As atopic eczema can cause your skin to become cracked and broken, there is a risk of the skin becoming infected with bacteria. The risk is higher if you scratch your eczema or do not use your treatments correctly.

Signs of a bacterial infection can include:

fluid oozing from the skin

a yellow crust on the skin surface

small yellowish-white spots appearing in the eczema

the skin becoming swollen and sore

a high temperature (fever) and generally feeling unwell

Your normal symptoms may also get rapidly worse and your eczema may not respond to your regular treatments.

You should see your doctor as soon as possible if you think your or your child's skin may have become infected.

They will usually prescribe antibiotic tablets, capsules or cream to treat the infection, as well as making sure the skin inflammation that led to the infection is well controlled.

Speak to your GP if these don't help or your symptoms get worse.

Once your infection has cleared, your GP will prescribe new supplies of any creams and ointments you're using to avoid contamination. Old treatments should be disposed of.

Viral skin infections

It's also possible for eczema to become infected with the herpes simplex virus, which normally causes cold sores. This can develop into a serious condition called eczema herpeticum.

Symptoms of eczema herpeticum include:

areas of painful eczema that quickly get worse

groups of fluid-filled blisters that break open and leave small, shallow open sores on the skin

a high temperature and generally feeling unwell, in some cases

Contact your doctor immediately if you think you or your child may have eczema herpeticum. If you cannot contact your GP, call NHS 111 or go to your nearest hospital.

If you are diagnosed with eczema herpeticum, you will be given an antiviral medication called aciclovir.

Psychological effects

As well as affecting you physically, atopic eczema may also affect you psychologically.

Preschool children with atopic eczema may be more likely to have behavioural problems such as hyperactivity than children who do not have the condition. They are also more likely to be more dependent on their parents.

Bullying

Schoolchildren may experience teasing or bullying if they have atopic eczema. Any kind of bullying can be traumatic and difficult for a child to deal with.

Your child may become quiet and withdrawn. Explain the situation to your child's teacher and encourage your child to tell you how they are feeling.

The National Eczema Society provides information about regional support groups, where you may be able to meet other people living with atopic eczema.

Problems sleeping

Sleep-related problems are common among people with eczema.

A lack of sleep may affect mood and behaviour. It may also make it more difficult to concentrate at school or work.

If your child has problems sleeping because of their eczema, they may fall behind with their schoolwork. It might help to let their teacher know about their condition so it can be taken into consideration.

During a severe eczema flare-up, your child may need time off from school. This may also affect their ability to keep up with their studies.

Self-confidence

Atopic eczema can affect the self-confidence of both adults and children. Children may find it particularly difficult to deal with their condition, which may lead to them having a poor self-image.

If your child is severely lacking in confidence, it may affect their ability to develop social skills. Support and encouragement will help boost your child's self-confidence and give them a more positive attitude about their appearance.

Speak to your GP if you are concerned your child's eczema is severely affecting their confidence. They may benefit from specialist psychological support.
